A Squidoo lens is a great way to earn a few dollars, usually you don't see much more than that, but it's easy money that can continue to generate month after month. The best month I've had was when one of my lenses made nearly $30. What a nice surprise to find that unexpected money in my PayPal account!
Here are a couple of my lenses (just to give you a couple examples):

If you have a hobby or interest, share it on a lens of your own! Set up your lens with eBay and Amazon widget's (using Squidoo's tools) and earn some dough on the side. Setting up a lens can be done in just a few minutes, to a few hours... depending on how much "stuff" you want to pack into it. Then you can promote yourself on your blog or website, with friends and family, through emails and phone calls. Update your lens on a regular basis and you'll find your rankings will be better. Visit other lenses and leave feedback and you'll find a steady growth of traffic. It's fun and pays!
